Technical Support

What is CSA Cement?

OREWORLD TRADE(TANGSHAN) is the perfect addition for mix designs that need to achieve high strengths quickly – as strong as 3,000 PSI in 60 minutes and an initial set time as fast as 20 minutes. It can be used with retarder additives to provide longer workability, while still achieving high early strengths, making this an ideal product for time-sensitive projects. OREWORLD TRADE(TANGSHAN) is a made in the USA product.
